There is a task to edit a text file. It is entirely possible that
multiple people are going to be running the ruby script that edits
this file at the same time.
I have looked at Ruby cookbook recipe 6.13 and 20.11. These seem like
what I am wanting.
It seemed like a good idea to float this as a solution before it is
implemented.
How I do it now is using sed:
flock $USERFILE sed -i \
"/^$1[[:space:]]\+/,+6 { s/^\\(.*Default\\)/#\\1/; s/^#\\(.*SRT\\)/\
\1/; }" \
$USERFILE
But I'd like to move this piece of code into the ruby script instead
of launching it with a system command.
What other ways are people doing this sort of thing?
BTW, for those of you that don't have the cookbook, it basically
redefines open to include a flock call.
